SPEGIFIGATION Application filed Hay 25,

Be it known that I, J AME's HARVEY LEIGH- TON, a fcitizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Glass-Faced Bricks or Building-Blocks, of which the following is a specification. 1

This' invention provides a glass-.faced brick or building-block of peculiarformation and involving novel process inits manufacture.'

The body of the building unit is porous and its sides rough, so as'to make a firm bond with the' montar, cement, or other binder and the face smooth, impervious, and lustrous.

In the manufacture of the article vthe body arid face are separately formed and welded or fused, so as to make, in effect, a unitary strucpressed together.

ture. The body iscomposed of material capable of being `softened by heat, so as to unite with the face by 'a welding action when both are rendered plasticl .or softened by heat and The face may be glass,

porcelain, or like vitreous4 substance and i's comparatively thin, so as t6 form a substan- 1 tial vfacing to the/brick or bldckf The. body is composed of sand, spar, alkali, and some while stillplastic is giventhe required shape and-welded to the glass facing, which has likewise-been softened by heat.

, In practicing theinventiongthe instrumentalties shown inthe accompanying drawings havey been devised. However, other wellknown means may be employed with equal advantage.

In the drawings, Figure 1 isa perspective` View of a building brick or block embodying the invention. Fig. 2` is a sectional-detail of the means 'for forming theblock, the same illustrating the "first step in the process of manufacture. Fig. `3 is a view similar to Fig. 2, showing a lump or mass of material forming the body of the brickl orblock placed in position for shaping and welding to the facing. Fig. 4 is a view similar to Figs. 2 and 3,.show

ing the completion of the operation.

forming part of LettersfPatent No. 7 56,971, dated April 12, 1904.

1903. Serial No. 158,699. (No model.)

Corresponding and like parts arereferred to in the following description kand indicated in all the'views of the drawings by thesame reference characters.

` Thebrick or building-block is shaped in a mold l, which may be of any form, size, and

construction. Plunger 2 is' arranged to operate in the mold for compressing the material and causing same. to conform to the shape f 'the lmold as well as enabling the requisite force for effecting welding of the body and facing (being conveniently and effectively applied. The facing 3 is of glass, porcelain, or like vitreous material, andconsists of comparatively thin plate. This facmg is softened lby the application ofheat 'and is forced into the bottom of the mold by plunger 2, as indicated in Fig.l 2.

The material-forming the body of thebrick or building-block ina softened or plastic state and in sufiicient quantity is' placed upon the mold, as indicated in Fig. 3, and is forced into the same by "descent of plunger 2, whereby the predetermined shape is imparted thereto and the body 4'We1ded to the facing 3, as indicated most clearly in Fig.'4. Within the purview of the in vention the body 4 may be 4 shaped in any manner and facing 3l applied and welded theretoby a-fused joint. The'fac.- ing 3 may be of any color and finish to present the desired effect.' The body 4 is porous and its sides rough, so as to insure a firm 'union Vof the cement or fmortar thereto.

Having thus described the invention, whatl is claimed as new isv A building unit composed of a facing of glass or like material and a vitreous body having a spongy or porous nature welded lto said facing by a fused joint, said bodycomprising sand, spar, alkalicand a metallic oxid mixed and heatedl to about 2,0000 to 2,5000 Fahrenheit, substantially as specified.J
